Hello, I'm Jerry Smit with the BBC News.
The UN Security Council has agreed to start work immediately on drawing up new sanctions against North Korea following its claim to have tested a hydrogen bomb. There is skepticism that Pyongyang's latest nuclear test, the fourth in a decade, was powerful enough to have been a hydrogen device. From Washington, here is Aleem Maqbool. “The White House says initial analysis is not consistent with the North Korean claims it tested a hydrogen bomb. Nevertheless, its condemnation of whatever nuclear test might have taken place was unequivocal. The UN Security Council held an emergency meeting when members said Pyongyang had threatened world peace. The Council resolved to come up with strong measures to deter North Korea in the future.”
